HPHT technology

We offer only diamonds grown by HPHT (High Pressure High Temperature) technology, which accelerates the natural process, improves it and makes it absolutely environmental friendly.

With the help of special cubic hydraulic press units, the HPHT method recreates natural geological conditions that occur at a depth of hundreds of kilometers in the Earth’s mantle. The conditions are a unique and powerful combination of extreme pressure and very high temperatures. To grow a diamond in a cubic press, the tiny natural or synthetic diamond seeds are carefully placed into the bottom of a growth cell. The layers of additional metal-solvent and carbon, in the form of graphite, are then delicately placed on the top of diamond seeds. The growth cell is then placed into the center of the cubic press and heated to 1,500 degrees C while being subjected to 50-60 kilobars. At that temperature and pressure the metal in the growth cell is melted and the graphite very slowly transforms through the liquid metal into our favorite form of carbon, a diamond crystal.

HPHT diamonds we offer are grown in controlled facilities by professional engineers, scientists and technicians using a modest amount of electricity and resources.

Diamond creation process is one of the most precise and difficult manufacturing techniques that humans have ever achieved. It took almost 50 years to develop the precision to grow routinely gemstone quality diamonds larger than one carat.

As a result of this process the lab grown diamonds have the same crystal structure, chemical composition and similarity of optical and mechanical properties with the mined diamonds.

HPHT technology has come so far to the level that now it is possible to produce up to 100 carat of rough diamonds delight of gemologists, jewelers and diamond connoisseurs around the world.

Following the nature process, our technicians additionally use impurities to create fancy color diamonds: boron to get fancy blue, nitrogen to get fancy yellow. Pink diamonds are the result of the diamond crystal lattice slight deformations due to various post growth treatments.
